# Single Degree of Freedom System-Video Simulation

Can anyone help me with some video simulations on vibrations in single degree of freedom system like the one in the link below

You should be a bit more specific about what exactly your problem is.

For one thing, this is harmonic motion with one degree of freedom.

Also, the initial conditions are:

x(0) ~= 4.45m

$$\dot {x(0)} ~= 0.6 m/s$$

I do not like this demonstration. They should have their neutral axis about the equilibrium position, not at around 4.5. They need to do a coordinate transformation.

You can easily see that this is a single degree of freedom by applying Gruebler's equation.
